Answer:
0.584 J/g°C
Explanation:
Using the formula as follows;
Q = m × c × ∆T
Where;
Q = amount of heat (joules)
m = mass of substance (g)
c = specific heat capacity (J/g°C)
∆T = change in temperature (°C)
According to the information in this question;
mass of substance (m) = 1050g
Initial temperature = 25.7°C
Final temperature = 30.4°C
amount of heat (Q) = 2880J
change in temperature (∆T) = (30.4°C - 25.7°C) = 4.7°C
Using Q = m.c.∆T
c = Q ÷ m∆T
c = 2880 ÷ (1050 × 4.7)
c = 2880 ÷ 4935
c = 0.584 J/g°C
The specific capacity of the substance is 0.584 J/g°C.
